01 - Using a mandoline slicer or a sharp knife, cut each potato into thin, even slices approximately 1/8 inch thick. Uniform thickness ensures consistent crisping during frying.
02 - Submerge the potato slices in a bowl of cold water for 10 minutes to draw out excess surface starch. Drain thoroughly and pat each slice completely dry with paper towels—moisture is the enemy of crispiness.
03 - Pour the vegetable oil into a deep fryer or a large heavy-bottomed pot. Heat the oil to 350°F (175°C), using a thermometer to monitor the temperature for optimal frying conditions.
04 - Working in small batches to avoid overcrowding, carefully lower potato slices into the hot oil. Fry for 3 to 4 minutes per batch until the chips turn golden brown and crisp. Remove with a slotted spoon and drain on a layer of paper towels.
05 - In a small saucepan over low heat, melt the unsalted butter. Pour in the hot sauce and whisk continuously until the mixture is smooth, well blended, and heated through. Remove from heat and set aside.
06 - While the chips are still warm, transfer them to a large mixing bowl. Sprinkle with garlic powder, smoked paprika, salt, black pepper, and cayenne pepper if using. Toss gently to distribute the seasonings evenly across all chips.
07 - Drizzle the prepared Buffalo sauce over the seasoned chips, tossing them gently to ensure every chip receives an even, light coating of the spicy butter sauce.
08 - Arrange the Buffalo chips on a serving platter immediately while still warm and crisp. Top with blue cheese crumbles or a drizzle of ranch dressing if desired, and scatter freshly chopped chives or green onions over the top. Serve right away for the best texture and flavor.
